To add a bit of vendor flexibility with various virtio based devices, allow the caller to check for a different device id. This adds a function pointer field to struct virtio_pci_modern_device to specify an override device id check. If defined by the driver, this function will be called to check that the PCI device is the vendor's expected device, and will return the found device id to be stored in mdev->id.device. This allows vendors with alternative vendor device ids to use this library on their own device BAR. Note: A lot of the diff in this is simply indenting the existing code into an else block.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
